The two pie charts illustrate the proportion of energy produced by five main sources in the years 1980 and 1990.

Overall, in the given time frame, oil accounted for the lion’s share of energy production even though it experienced a decrease. Coal as well as nuclear power showed growth in energy production and its reverse was applicable to natural gas.

In 1980, oil was the dominant producer of energy, accounting for 42%, which declined considerably by 9% to a third of the total(33%) in 1990. In stark contrast, generation from coal rose by 5% from 22% to 27%. The figures for natural gas reduced marginally from 26% to a quarter(25%).

Conversely, hydroelectric power remained completely static, contributing 5% in both the years which represented the smallest fraction. Finally, nuclear power climbed from 5% to a tenth of the total(10%) after a decade.

Task Response

The report fully satisfies the requirements of the task. It provides a clear overview of the main trends and effectively highlights the key changes between the two years. The data is presented accurately and is well-organized into logical paragraphs. The use of varied vocabulary and sophisticated sentence structures enhances the quality of the report. The report falls short of the required 150 words.

Coherence & Cohesion

The report is well-organized and easy to follow. The use of cohesive devices such as 'Overall', 'In stark contrast', 'Conversely', and 'Finally' helps guide the reader through the comparison effectively. The paragraphing is logical, separating the overview from the specific details. To reach a higher band, ensure that the transition between the overview and the body paragraphs is even more seamless, perhaps by grouping related trends more tightly.

Lexical Resource

The writer demonstrates a good range of vocabulary, using effective phrases like 'the lion's share', 'dominant producer', and 'declined considerably'. There is also good use of synonyms to avoid repetition (e.g., 'a third', 'a quarter', 'a tenth'). To improve, aim for even more sophisticated lexical variety when describing changes and proportions to ensure the language feels entirely natural and varied throughout.

Grammatical Range & Accuracy

The report uses a variety of complex structures, including subordinate clauses and comparative forms. Most sentences are error-free and convey meaning clearly. There are minor issues with phrasing and punctuation (such as the spacing around parentheses), but these do not impede communication. To improve, focus on refining the precision of sentence structures to ensure complete grammatical control in every sentence.
